[SPOILER ALERT: don't read past post #1 in this thread, or you may see people giving away quiz answers below.]
Added: another quiz to EcoModder's...
... series.
Test your car recognition skills & see if you can beat the average score.
Third quiz in the series: identify these (relatively) slippery production cars with drag coefficients of 0.28 or better. A somewhat international selection of vehicles from past and present makes up this quiz.
